Backup running back Mike Goodson, who also has a high ankle sprain, is not able to start running yet. Both running backs are essentially out for Sunday’s game, but Allen won’t make that official until Friday. Marcel Reece will start.

Allen said safety Tyvon Branch’s neck injury is a concern. He and WR Darrius Heyward-Bey (hamstring) need to practice Friday to show they’re up to playing Sunday.

Fourth-year veteran Mike Mitchell would step in for Branch. “(Mitchell) is a passionate player,” Allen said. “He needs to slow his heartbeat down” and has started to play more under control.

Safety Matt Giordano returned to practice after leaving last week’s game with a concussion.
